METHOD FOR COMPLIANCE WITH A TRAFFIC CONTRACT OF A PACKET STREAM OF A PACKET TRANSPORT NETWORK WITH VARIABLE LENGTH

摘要

The present invention relates to a method of bringing a packet stream of a variable length packet transport network into compliance with a traffic contract. Said method is of the type which consists in each arrival of a packet, in comparing the time of this arrival with a theoretical arrival time and, if this arrival time is earlier than said theoretical time by more than the defined jitter tolerance in said contract, destroy said package or ignore it, otherwise reissue said package and then determine the theoretical arrival time for the next package. According to the invention, it is characterized in that, to determine said theoretical arrival time for the next packet, it consists in adding a time ti which is linked to the present packet i and which is a function f of the theoretical arrival time TATi and of the real time of arrival thetai of said packet i to an interpacket time Ti which is a function g of the time negotiated per unit of length T defined in said traffic contract and of the length lambdai; from the current package i. /P
